Inventor: BIANCHI DIANA W
IPC: G01N33/50
Filed: 1990-11-13
Abstract: A method of isolating fetal nucleated cells, particularly fetal nucleated erythrocytes, from a maternal blood sample, by means of an antigen present on the cell surface of the fetal erythrocytes. A method of detecting fetal DNA of interest, which is a gene or gene portion associated with a disease or condition, a chromosomal abnormality or sex-specific DNA, in a maternal blood sample. The presence or absence, as well as the quantity of fetal DNA of interest in a maternal sample can be determined. The claimed method of detection can be used prenatally or postnatally and is particularly useful because it is non-invasive and can be carried out early in pregancy. <IMAGE>

Abstract: The invention relates to a construction element (1) for a soundproofing shed, as is employed for the ground testing of jet-engined aircraft. Such sheds have perforations, extending in the shed transverse direction, for admitting fresh air and mutually spaced layers of sound-absorbing material (10, 11) which are arranged on the inside of the shed roof and between which are formed air passage gaps for fresh air entering the shed space. The present invention solves the object of being able to carry out erection of such a soundproofing shed within a shorter time and more cost-effectively. The solution of this object according to the invention provides, in a preferred embodiment, prefabricated construction elements (1) for building a shed, which contain, in the shed longitudinal direction, stepped roof-slab elements (2) retained by a supporting structure (5), as well as a first (10) and second (11), mutually spaced element made of sound-absorbing material. By lining up and connecting the supporting structure (5) in the shed transverse and longitudinal direction, inlet air gaps extending over the entire roof length in the shed transverse direction and passing between the damping layers are produced. Since the shed roof can be assembled from prefabricated building elements (1), the soundproofing shed can be erected within a short time and cost-effectively.

Abstract: In the indicated process and by means of the indicated apparatus, fused silicon is produced continuously or in phases and zonally filled into a mould, in which it is caused to solidify zonally. The temperature conditions in the solidification zone are here controlled with the aid of a movable heating zone, by means of which the crystallisation front is caused to follow the rising level in the mould, the level in turn being controlled via the fusion rate of the silicon. Multicrystalline silicon blocks can be obtained, in which the columnar single-crystal domains within the blocks extend approximately vertically because of the planar shape of the crystallisation front, and which represent an excellent solar cell base material having high diffusion lengths and service lives of the minority charge carriers, from which material solar cells of correspondingly high efficiencies can be manufactured. …<IMAGE>…

Abstract: A yarn transfer arrangement in a yarn winding machine (10) comprises two part-circular guide plates (28,29)which, when an empty tube (17) has moved to the winding position, move from a non-operating position, spaced apart on opposed sides of the winding position of the machine (10) by a distance greater than the diameter of a full package (15), to an operating position in which the plates (28,29) surround the empty tube (17) apart from an entry aperture (30) and an exit aperture (31) allowing the yarn (14) to travel to and from the empty tube (17). One guide plate (28) causes the yarn (14) to have sufficient wrap around the empty tube (17) that, on operation of a cutter (32) disposed on the other guide plate adjacent the exit aperture (31), the cut yarn (14) end is entrained around the empty tube (17) between it and the other guide plate (29), and winding of a package (15) on the empty tube (17) is thereby initiated. The guide plates (28,29) are then moved back to the non-operating position.

Abstract: A self-expanding stent assembly (10) consisting of one or more z-stents (11,12) connected to one another and covered by a flexible sleeve (13), which can be made from either nylon, plastic or another suitable material. The stents are formed of stainless steel wire arranged in a closed zig-zag configuration which includes an endless series of struts (14) that are joined by an equal number of joints (17). The stent assembly is compressible into a reduced diameter size for insertion into, and possible removal from, a body passageway. After being properly positioned within a body passageway, the stent assembly is allowed to expand to its larger diameter shape, wherein the sleeve is pressed against the walls of the passageway by the stents. One application of the invention includes dilating a biliary duct which has been occluded by a tumorous growth. The advantage being that the sleeve prevents the tumor from growing between the gaps created by the stent which would otherwise restenose the passageway. Another intended application is to repair aneurysms. In this configuration, the stents are postioned on either side of an aneurysm, and the sleeve forms and artificial arterial wall which spans the aneurysm.

Title: Regulated bifurcated power supply.
Inventor: PARKS ROBERT A
IPC: G05F1/56
Filed: 1990-12-14
Abstract: A regulated power supply employs two separate sources of power which are serially connected by a variable impedance element, such as a transistor, connected between the two power sources. Output voltage of the power supply is equal to the sum of the individual power supply voltages minus a voltage drop across the variable impedance element. A sensor circuit employing standby and active mode branches is coupled between output terminals of the power supply for control of the variable impedance element. The active branch of the sensor is switchably connected to an output power terminal of the supply so as to be operative only during the active mode. The standby branch comprises a resistive network coupled to a reference diode while the active branch comprises a feedback amplifier coupled to the reference diode.

Abstract: A sample and a magnetic carrier having a surface immobilized with a substance specifically bonded to an antigen or antibody to be detected are mixed in a reaction vessel. A magnetic field is applied to the reaction vessel to form a precipitation image on the wall surface of the reaction vessel. A strength of the magnetic field on the wall surface is distributed with a predetermined gradient from an arbitrary area on the wall. It is determined whether the antigen or antibody to be detected is present in the sample in accordance with the shape of the precipitation image. In order to distribute the strength of the magnetic field with a predetermined gradient from an arbitrary area on the wall surface, a magnet is arranged outside the reaction vessel so that the distance between the upper surface of the magnet and the wall surface of the reaction vessel is gradually increased, or a magnet having a gradient magnetic field is arranged outside the reaction vessel. By adjusting the distribution of the strength of the magnetic field on the wall surface, a precipitation image is formed without being dependent on the shape of the reaction vessel. In formation of a precipitation image on the basis of the distribution of the strength of the magnetic field on the wall surface, the wall surface may be flat. In this case, it is very easy to stably maintain the precipitation image after its formation.
